The Lowdown
Right folks, ol’ Rusty here. Let me level with you straight up about Kennebunk Beach. If you’ve got your sights set on a proper surf session over the next couple of weeks, you’re gonna need a whole lot of patience. This is a bit of a flat spell, so don’t be holding your breath just yet.
For the first week, from Wednesday the 26th right through to the end of August, it’s pretty grim. We’re looking at tiny, weak waves pushed around by less-than-ideal winds. The water’s hanging around 66°, which is a touch warmer than usual for this time of year, but that’s the only bright spot. The combined energy is puny, down in the double digits most days, and the best you’ll see is a bit of clean surf on the 29th Saturday morning with a light offshore breeze, but the swell is barely 2ft. Don’t bother.
Things don’t get much better heading into the first week of September. We’ve got a long stretch of nothing. The 1st and 2nd might offer a glassy moment or some clean conditions, but the swell is still tiny. There’s a bit of a pulse coming in on the afternoon of the 2nd with a 4ft swell from the SE and an 11-second period, pushing the combined energy up to 378, but it’s still being called “poor surf conditions.” The offshore wind will keep it clean, but the energy isn’t really focused here.
Now, look ahead to the 6th of September. That’s your best bet. Sunday the 6th is a standout. The morning and afternoon both show a 5ft swell from the East with a long 11-second period. The combined energy is a solid 457 and 437, which is decent grunt. The wind is a clean, light offshore breeze, keeping the waves tidy. This is the kind of day that will actually have some shape and push. If you’re a confident surfer, this is the one to aim for. It’s a bit of a long-range look, so don’t set your watch by it, but it’s the only real window of opportunity we’ve got.
The 7th of September still has some size at 4ft and glassy conditions in the morning, but it’s a step down from the Sunday. After that, we’re back to small, choppy conditions with moderate wind. Honestly, for most of this forecast, the setup is so weak and choppy it looks more interesting for kite surfing than paddle surfing. But if you’re patient, the 6th is the day.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
